The 'Don Jon'' star, who also wrote and directed the film, thinks people need to take more responsibility for how they let different types of media, including porn, affect them.

Speaking at an official gala screening of the movie at the Odeon cinema in London's Leicester Square as part of the 57th BFI London Film Festival on Wednesday night (16.10.13), the 32-year-old actor exclusively told BANG Showbiz: ''I don't think any particular media is inherently bad. It's on us as individuals to interpret the media that we consume, whether that's pornography, movies, television or commercials.''

The romantic-comedy tells the story of a young man, who develops unrealistic expectations from watching porn and works to become less selfish, but Joseph doesn't think its subject matter is controversial.

He said: ''I think everybody's always talking about sex. From the ancient Greeks to Shakespeare to now. Don Jon is sort of a timeless classic story.''
